This study investigated the effects of congenital brain injury alone, or in combination with sensori-neural hearing loss, upon figure-ground thresholds for spondees in young children.
Forty-eight subjects were selected from four diagnostic categories: (1) brain injured, normally hearing; (2) brain-injured, hearing-handicapped, (3) non-brain-injured, normally hearing; and (4) non-brain-injured, hearing-handicapped. Brain-injured and non-brain-injured subjects were matched for pure-tone thresholds. Selected spondees were presented bilaterally, first in quiet then in a background of white noise.
Results indicated no effect upon speech thresholds by brain injury, and no apparent interaction between brain injury and hearing impairment.
